Specification of Letters Patent.

Patented Sept. 30, 1913.

Application filed August 22, 1912. Serial No. 716,354.

To all whom it may concern:

Be it known that we, ISADORE COHEN, a subject of the Emperor of Russia, and ALEX- ANDER LANDSBERG, a citizen of the United States of America, both residents of New York, county and State of New York, have invented certain new and useful Improvements in Eyeleting-Machines with Automatic Feed, of which the following is a full, clear, and exact specification.

This invention has for its principal object to provide an apparatus for binding loose leaves of paper by means of eyelets and for punching the holes adapted to receive the eyelets and thereafter to roll up the lower flanges of said eyelets on the undersides of the paper sheetsor staples in such a manner that the paper is securely held together be tween the two flanges of the eyelet.

Another object of the invention is toprovide a machine which by one action of the plunger perforate; the paper and forms the lower flange of the eyelet.

A further object of this invention is to provide a machine in which the eyelets are fed through a drum into their working position above the anvil and below the punching tool in such a manner that one movement of the plunger is sufiicient to bring the eyelet into its working position, to perforate the paper and to roll the lower flange of the eyelet up.

-A still further object of the invention is to provide an eyeleting machine, the plunger of which is capable of executing downward movement to enable the punch to perforate the paper, without operating upon the eyelet which in this case is in the drum withdrawn from the anvil.

Other objects and advantages of our apparatus will become apparent from the following description and it will be understood that changes in the machine as shown and described may be made within the scope of the invention without departing from the spirit thereof.

In the drawing, forming a part of this specification in which like numerals of reference indicate similar parts in the several views: Figure 1 shows the machine in front view. Fig. 2 is a side View thereof showing an eyelet in position to be operated upon, and Fig. 8 is another side view showing the drum containing the eyelet withdrawn from the punch which is in its depressed position for 'making a hole through a staple of papers.

The machine is cheaply made of metal and of very simple construction.

It consists of a base plate 10, upon one side of which a curved arm 11 is mounted carrying at its front end a laterally disposed ing loosely guided in a central vertical opening of the sleeve 12. At the upper end of said plunger sleeve 19 a vertical flange 20 is formed to receive the lower ends of two links 21, 21. A pivotal pin 22 extends through the central part of said flange on the sleeve 19, and said links, and securing pins 28 or the like pass through the outer protruding ends of said pin 22 and secure the parts in position. The upper free ends of said links 21, 21 form a bearing for the pin 24 constituting a pivotal connection for the plunger bar 25 between these links, and cross pins 26 serve to secure the parts in position. The outer end of said plunger bar 25 is provided with a suitable handle 26 secured to the bar in any well known manner. The bar 25 may be made of one piece of metal or may be divided intermediate its ends so as to form a joint 27 to allow a folding of the bar upon itself for packing purposes or for the purpose of preventing the bar from forming an obstruction upon a desk, etc.

Near its outer end the plunger bar is provided with a suitable opening adapted to receive a small shaft 28, one end of which is firmly secured in the upper end of the arm 13 by means of a nut 29, while the other end forms the pivot or'journal of an arm 30, depending from said shaft 28. The bearing of said arm is mounted on said shaft in such a manner that its movement is retarded by a friction washer .31, which is held against the bearing of the arm by a 45 A .shaped groove 42.

, ward movement to said arm 30.

outer end of the plunger bar is set off as shown at 35 and is provided with a hole 36 in which one end of a spiral spring 37 is secured, the lower end ofwhich is secured to a pin 38 laterally projecting from the arm 11. Intermediate the hole 36 and the shaft 28 the plunger bar 25 is provided with a laterally extending pin 39 adapted, when the handle 26 is raised, to impart an in- At its lower end the arm 30 carries at an inclination to its vertical axis an eyelet guide block 40 removably secured to said 'arm by a set screw or the like 41 said'guide block being provided with a 'T-shaped groove d2 adapted to receive the eyelets to be used. A spring 43 has one of its ends secured to the outer side of said guide block by means of a screw44, or the like, while its other end is rectangularly bent as at 45 and embedded in a horizontal notch in the forward .end of said guide block, and projecting across the lower end of said T-shaped groove so as to yieldingly arrest the lowermost eyelet. It is clear that the lowermost of the eyelets within the guide block will be held by the rectangular bent portion 45 of the spring 4L3 in position to be operated upon above the countercheck 17 and below the punch 18. A suitable paper guide '47 is adjustably secured to the base plate 10 by a set screw 48. It is clear that oneor more of saidpaper guides or'gages may be employed, or a guide of larger size than the one shown may be secured in' front of the anvil; The eyelets to be operated upon are inserted in a grooved rod or feeder 50, adapted to be introduced above into a T- A small projection 52 is formed approXi- .inately in the center-of the outer wall of the sleeve 12 oppositely disposed to the arm 30, in order to limit the downward movement of said arm. Instead of the feeder 50 a chute or the like may be firmly secured to the upper'edge of the guide block 40 or other similar cont-rivances may be used to feed the eyelets into 7 the guide block.

The operation of the machine islthe following: The eyelets having been brought into the grooved rod or feeder 50 are fed by their own gravity and slide down into the T-shaped groove 4.2 of the guide block until the foremost eyelet strikes the end 45 of spring 413, assuming the position of Fig.

2 ready to be operated upon by thev punch which at the depression of the plunger bar will perforate the paper and roll up the 7 lower flange of the eyelet upon-the underside thereof thus securely binding the sheets together, or if one sheet is used only making a hole in the paper, the edge of which is lined by a metal ring.

' If it is desired for any purpose, such, for

instance, as when a very thick staple of papers is to-be operated upon, to punch the holes without operating upon the eyelets, the plunger bar is pressed only part way down, carrying the pin 39 away from the arnr 30, when the said arm may be manually swung outward on its pivot to substantially the position shown in Fig. 3 whereby the eyelet held in the'inner end of theguide block will be removed out of the path of the punch. The arm 30 will be heldin thisp'osition by means of the friction washer 31 and screw head 32', and the plunger b'ar may be reciprocated to cause the punch to operate, without acting upon the eyelets, provided said plunger bar is not forcibly raised high enough to cause the pin 39 to press the arm 30 inward 'far enough to -move'the forward end of the guide block 40 with an eyelet therein into the path of the punch. The friction of the washer 31 on the arm30 issufiicientto prevent the spring 37, without manual assistance, from causing the pin 39 on the plunger bar to press the arm 30 inward to'the position of Fig.1, sothat the parts will be maintained in the punching positions so long as the plunger bar is not raised high enough to cause said pin 39 to press the arm 30inward' to the position of Fig. 1.

To resume the operation of both punching and eyeleting, it is only necessary to raise the plunger bar to its highest position, as shown in Fig. l,which will bring the eyelet in the inner end of the guide block into the path of the punch to be operated upon thereby As the plunger bar-is pressed downward to near-the end of its stroke, the yielding pin 18 enters the eyelet in advance of the punch reaching. it. At this point the curved out departing from the spirit of the invention.

Difierent sizes and styles of eyeletsmay be used in this machine, by simply changing the feeder and guide block for others of proper form, which changes will not depart from the spirit and scope of the invention.

Having thus described our invention, what we claim is:

1. An eyeleting machine of the character described, comprising, in combination, a punch, an exchangeable eyelet feeding receptacle, a vertical swinging arm carrying said receptacle at its lower end, means adapted to move said arm into feeding position when the punch is moved upward, means operating simultaneously with the eyeleting operation to move the arm out of feeding position, and a frictional pivotal support for the vertical swinging arm to hold said feeding receptacle out of feeding position during punching operation.
